Hello Guys!!!

Can someone help me please with this problem??

I created an Analysis Services´s calculated member in order to inform how many itens I have in the children´s level of a dimension. So, for all members of the Product dimension, for exemple, there is no problem. But, when the users selects just some members, the total is still the same of all members, not only the selected ones.
The formula I wrote is:
sum([product].currentmember.children,[Measures].[Itens])
There is a way to put some filter in this code in order to returns only the total of the selected members?

For example:
1) without any filter:
Product_Group Aticle Itens
123 T-Shirt 10
123 Socks 5
123 Total 15

2) with a filter:
Product_Group Aticle Itens
123 T-Shirt 10
123 Total 15









Thank you very much!!!!
